Conclusions

  1. 1.

    The dependence of the hydraulic resistance of a grid on a change in the ratio δ/d0, at d0 = const, has been confirmed experimentally.

     
  2. 2.

    It is shown that, contrary to the opinion of a number of investigators, the resistance of a grid depends on the change in the ratio δ/d0, at δ = const, that is, it depends on the diameter of the openings in the grid.

     
  3. 3.

    Formula (6) has been obtained for calculation of the hydraulic resistance of dry grids, taking account of the dependence of the resistance on the diameter of the openings and the thickness of the grid.
